History of the Peloponnesian War

About the same time the Athenians that were on the coast of Sicily sailed unto Locris and, landing, overcame such as made head and took in Peripolium, situated on the river Halex.

The same summer, the Aetolians, having sent their ambassadors, Tolophus, an Ophionian, Boryades, an Eurytanian, and Tisander, an Apodotian, to Corinth and Lacedaemon, persuaded them to send an army against Naupactus for that it harboured the Athenians against them.

And the Lacedaemonians, towards the end of autumn, sent them three thousand men of arms of their confederates of which five hundred were of Heracleia, the new-built city of Trachinia. The general of the army was Eurylochus, a Spartan, with whom Macarius and Menedaeus went also along, Spartans likewise.

When the army was assembled at Delphi, Eurylochus sent a herald to the Locrians of Ozolae both because their way lay through them to Naupactus, and also because he desired to make them revolt from the Athenians.

Of all the Locrians the Amphissians co-operated with him most, as standing most in fear for the enmity of the Phoceans. And they first giving hostages induced others who likewise were afraid of the coming in of the army to do the like: the Myoneans first, being their neighbours, for this way is Locris of most difficult access; then the Ipneans, Messapians, Tritaeans, Chalaeans, Tolophonians, Hessians, and the Oeantheans. All these went with them to the war. The Olpaeans gave them hostages but followed not the army. But the Hyaeans would give them no hostages till they had taken a village of theirs called Polis.
